Has anybody any knowledge of external JetDirect devices which can be used to
connect a number (3) of printers to a network?
 
A customer is using Unispool to print from his HP3000 to network attached
printers.  In addition to the IP address, the TCP port number is required for
the Unispool configuration.  With the internal JetDirect card, the port number
is 9100.  While this value permits access to the first device on the external
box, we have so for been unable to identify values for the other connections.
 
Any help in identifying the port values would be greatly appreciated.
